PAPER-REGISTERING INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 625,092, dated May 16, 1899. Application filed June 2, 1898. Serial No. 682,816. (No model.)

To aZZ whom, it may concern:

Be it known that I, TALBOT O. DEXTER, a citizen of the United States, and a resident of Pearl River, in the county of Rockland, in the State of New York, have invented new and useful Improvements in Paper-Registering Instruments, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the type of paperregistering mechanism shown in my Letters PatentNo.575,150,dated Januaryl2,1897,and to analogous registering mechanisms provided with electromagnetically-controlled means for drawing the sheet toward the registering instrument, which is equipped with a point or attenuated tongue entering into a slit in the sheet and thereby arresting the movement of the sheet at its registering position, the circuit maker and breaker being simultaneously actuated to deprive the instrument from the aforesaid electromagnetic force. In said prior the weight of the aforesaid arms.

paper-registering mechanisms the arm which carries the pointing or registering instrument proper is attached to the arm which carries the drop-roller, and in consequence thereof the magnet is compelled to lift both of said arms. In practice I have found this to be very objectionable for several reasons, to wit: First,it required averypowerful magnet to lift Secondly, when the registering instrument was required to operate on paper possessing a stiffness which required considerable pressure of the pointing instrument to depress the sheet in front of the slit-opening bridge, then said resistance of the paper prevented the droproller from being pressed onto the sheet with sufficient force to cause the subjacent rotary roller to obtain the requisite frictional hold on the sheet to move it, and, thirdly, when a spring was employed to bear on the supporting-arm of the drop-roller to overcome the aforesaid resistance a further increased power was required of the magnet to overcome the force of the spring in addition to the weight of the aforesaid two arms with the devices carried thereon. All of these diiliculties and objectionable features are obviated by my present invention, which consists, essentially, in the combination of the drop-roller and the pointing instrument supported movablyindependent of each other to and from the plane of the sheet-supports, a lever provided with means forlifting the droproller individually, electromagnets actuating said lever to lift the drop-roller, a rock-arm provided with means for lifting jointly the drop-roller and pointing instrument, and mechanisms imparting motion to said rockarm; and the invention also consists in certain novel features of the details of the reg istering mechanisms, as hereinafter fuilly described, and set forth in the claims.

In the annexed drawings, Figure l is a vertical longitudinal section of a paper-folding machine equipped with my improved paperregistering instrument. Fig. 2 is a plan View of the same, taken beneath the plane indicated by the dotted line X X in Fig. 1. Fig. 3 is an enlarged plan view of said registering instrument. Fig. 4 is an enlarged vertical section on line Y Y in Fig. 3. Figs. 5 and 6 are enlargedfragmentary side views of said instrument, showing the same in different 0perative positions. Fig. 7 is an enlarged vertical transverse section taken directly back of the shaft to which the arm of the registering instrument and drop-roller arm and their actuating-levers are connected; and Fig. -8.is an enlarged longitudinal section of the automatic wire-take-up device, taken on line Z Z in Fig. 6.

Similar letters and numerals of reference indicate corresponding parts. i

A A represent the paper-folding rollers, and A the blade which tucks the sheet into the bite of said rollers in the usual and wellknown manner. The mechanisms for operating said blade vary in their constructions in different machines, and being immaterial to my present invention they are omitted in the drawings hereto annexed.

a a denote the usual tapes which convey the paper tothe folding-rollers A A, and a a are the bars which support the paper beyond said folding-rollers.

B designates the gage or front stop which arrests the movement of the paper delivered onto the folding-machine.

Preparatory to folding the sheet by the rollers A A said sheet is to be registered or properly adjusted in its position to bring the predetermined line of folding directly over and parallel with the bite of the folding-rollers. The purpose of my present inventionis to automatically effect said registering of the sheet in a positively accurate and expeditious manner, and for this purpose I employ a registering mechanism constructed as follows:

Upon the sides of the main frame D of the folding-machine is supported a stationary cross-bar 0, upon which is mounted at right angles the supporting-bracket D of the registering instrument. In connection with said instrument I employ the gage B, which is arranged to intermittently recede from its sheet-arresting position to permit the sheet to receive a secondary forward movement, during Which the point of the registering instrument is caused to enter a slit made in the paper for that purpose. Said movement may be imparted to the gage by the same mechanism as shown and described in my Letters Patent hereinbefore referred to and as illustrated in the drawings hereto annexed, in which F represents a rock-shaft extending across the machine and, supported in suitable bearings on posts F, mounted on the main frame D. An arm F secured to the end of said shaft, has pivoted to its free end a roller by which it bears on a rotary cam F which imparts oscillatory motion to said arm. Two other arms G G are fastened in suspended positions to the shaft F and are connected at their lower ends to blocks F attached to the outer ends of bars G, which ride with their inner ends on supporting-rollers G Upon the said bars is ad j ustably supported the gage B, which is provided with screw-threaded eyes through which pass the screw-threaded portions of longitudinal rods H, journaled in the blocks F To the outer ends of the screws H are fastened worm-gears H, which engage corresponding gears 11 secured to a transverse shaft H which is journaled to arms projecting from the blocks F The end of the shaftH is provided with a hand-wheel H for turning said shaft and thereby imparting motion to the screw-rods H. In this manner the gage B is adjusted in its position to conform to different-sized sheets fed into the machine.

To the inner end of the bracket D is fastened a transverse shaft 0, which is formed with an extension 0 projecting from one side v of the bracket for the purpose hereinafter explained. Upon said transverse shaft is loosely mounted a lever 0 which extends upward therefrom and has fastened to its upper end the armature 0 which faces the magnet I, mounted on the bracket D. Adjacent to the hub of the lever c is the hub of the arm (1, to the free end of which is pivoted the droproller R. Said arm is loosely or pivotally mounted on the shaft 0 and has a lug (1 projecting from its hub. A similar lug a pro-. jects from the hub of the lever and bears upon the top of the lug d. To permit the said lever to be adjusted to carry the arma= ture a at a proper distance from the magnet I, a set-screw c is inserted vertically in the lug c and may be made to bear on the lug d, if necessary. Adjacent to the side of the droproller arm (1 is a longitudinal arm (1 also loosely mounted on the shaft 0 and provided on its hub with a lug 61 by which itbears on the lug d, as more clearly shown in Fig. 7 of the drawings.

At the sideof the hub of the arm 01 is a rock-arm D mounted loosely on the shaft 0 and provided with a rigid lug D which is fastened to the lug d by a screw D or other suitable means, and thus causes the arm d to move synchronously with the rock-arm D Said rock-arm derives its motion from another rock-arm D with which it is adjustably connected by a screw-rod D which is pivoted at one end to the arm D and passes with its screw-threaded opposite end through a collar D pivoted to the arm D. By means of nuts D on said screw-threaded portion of the rod at opposite sides of the collar D the distance between the free ends of the two rock-arms can be increased or diminished, as may be required, to cause the-free end of the longitudinal arm (1 to be moved the proper distance toward and from the plane of the paper-supporting bars a.

The rock-arm D is fastened to a transverse shaft d journaled in the bracket D and extending to the side of the main frame D, where it has attached to it a lever D", the free end of which has pivoted to it a roller by which it bears on a rotary cam D Said cam is shaped with two steps to impart to the rock-arms D and D two successive increased thrusts, and thereby cause the longitudinal arm 61 to receive two successive increased lifts for the purpose hereinafter explained. 011 said longitudinal arm is mounted the registering instrument proper, consisting of a vertical bracket 6, riding on a guide 8', extending from the end of the arm at and adj usted longitudinally thereon by a screw 6 journaled in suitable bearings on the arm and passing through a nut e on the bracket (2. To the said bracket, beneath the guide a, is pivoted a vertical lever 6 the foot of which is provided with the point or automatic tongue 6 for engaging the slit made in the paper for that purpose. Said lever is insulated from the bracket 6 by the pivot-screws c bearing on a rubber hub 6 secured to the lever. On the upper end of this lever is the terminal 6 facing the terminal a and held normally out of contact therewith by a counterbalance 6 connected to said end of the lever. The terminal 6 is attached to the bracket 0 and is insulated from the pivoted end of the arm d which is formed separate from the free end of the arm and spliced thereon, with an insulating-washer e interposed at the splice.

The current passes from the terminal e through the bracket 6, guide 6, and adjacent portion of the arm (1 and is thence conducted to the magnet I by an insulated wire 1, at-

tached at one end to a binding-screw 2 on the free end portion of the arm d and at the opposite end to a binding-plate 3 on the bracket D, and a wire 4 extends from said plate to the magnet I.

To allow the electric connection of the ter-' I ininal e to adjust inself simultaneously with the longitudinal adjustment of the bracket 6 on the guide 6, I attach to the side of said bracket a plate f and interpose an insulatingsheetf between them. On astud f projecting from said plate, is pivoted a spool f which is hollow and has in its interior a spiral spring f connected at one end to the hub of the stud and at the opposite end to the spool, as shown in Fig. 8 of the drawings. A coiled wire 5 connects the .lever e to the plate f, and a wire 6 is wound upon the spool f and extends to a binding-post '7 on the bracket D.

r In shifting the bracket e on the guide 6 in the operation of adjusting said bracket to its required position the coiled wire 5 will accom modate itself to said adjustment and the spring-adjusted spool f will automatically wind or unwind the wire 6, according to the direction in which the bracket 6 is shifted. A wire 8 is run from the binding-post 7 to the battery P, from whence another wire 9 is extended to a binding-post10,and a wire 11 leads from this binding-post to the magnet I.

Directly under the drop-roller R is the rubber-faced roller R, rigidly secured to a transverse shaft g, which receives rotary motion by means of a suitable train of gears O. The roller R is thereby caused to turn with the top portion toward the adjacent side of the frame D, and when the sheet is pressed in contact with said roller by the drop-roller the sheet is caused to be drawn toward the side of the machine by the frictional hold of the roller R. I

To allow the pressure of the drop-roller to be adjusted for operating on paper of different stiffness, I employ the spiral spring h, which is connected at one end to a stud h, fastened to the drop-roller arm d and has its opposite end wound around the shaft extension 0, hereinbefore described, and fastened to a collar 71. as shown more clearly in Fig. 7 of the drawings. Said collar is mounted loosely on said shaft extension and provided with notches it, adapted to engage a pin or lug i, projecting radially from the shaft eX- tension. By pushing the collar toward the bracket D, so as to release said collar from the lugs t' 'i, then. turning the collar, so as to wind up or unwind the spiral portion of the spring It, the tension of the spring can be regulated as may be desired, and in this adj usted condition it is then retained by allowing the collar to again interlock with the lugs In front of the registering-point e is the bridge j, which serves to open the slit in the sheet to insure the entrance of the point a tering the sheet.

In the operation of the described registering-machine the arms (1 and d are lifted to their greatest elevation to allow the incoming sheet to be moved freely to the gage B, to which it is carried by the tapes (1. a. gage at thattime is in its nearest position to the folding-rollers and arrests said movement of the sheet. The aforesaid lifting of the two arms is efiected by the rock-arm D pressing by its lug D upon the lug d of the arm 01 and causing the lug d to press upon the lug d of the drop-roller arm (2. As soon as the sheet has been arrested by the gage B the latter recedes, and the rock-arm D is actuated to allow both arms cl and d to descend. This causes the drop-roller R to press the sheet into frictional contact with the roller R, and at the same time the bottom of the point e is caused to press upon the sheet in front of the bridge j. The aforesaid frictional hold of the roller R on the sheet draws the sheet toward the registering instrument, and in this movement the slitted port-ion of the sheet is drawn over the bridge j, which serves to open the slit, so as to allow the registering-point e to readily enter the slit. The edge of the slit coming in contact with the lower end of the lever e tilts said lever and thereby brings the terminal 6 in contact with the terminal a. The circuit is thus closed, and the magnet I is caused to attract the armature o and move the lever c sufficiently to lift the drop-roller arm (:1 by the pressure of the lug 0 upon the lug d. The friction-roller R is thereby deprived of its hold upon the sheet and leaves the sheet in its registered position. The rockarm D is then actuated sufiiciently by the cam D to lift the arm d so as to cause the point e to lift the portion of the sheet hanging on said point. This allows the foldingrollers AA to draw the sheet into the bite of said rollers without danger of tearing the sheet during the travel of the slitted portion of the sheet across the bridge j. After the sheet has passed through the bite of the foldin g-rollers the rock-arm D receives its second impulse from the cam D and thereby lifts jointly the two arms d and d still further to insure free passage of the next incoming sheet under the registering-point e and droproller R. It will be observed that this second lift is effected mechanically and positively without the aid of the magnet, which latter is only required to impart the first lift to the drop-roller arm, and therefore my present improved registering instrument does not require the strong electric current, as theregistering instrument shown in my patent hereinbefore mentioned.
